[Control of the rear foot in lateral movements in sports]

The goals of this investigation were to establish the frequency distribution of different movements in various ball sports (1) and to test the influence of altered shoe sole constructions on the stability in lateral breaking movements (2). Firstly, a video analysis was carried out to establish the frequency distribution of different movements in sporting activities such as volleyball, basketball, team handball and football (soccer). It is shown that a selected number of lateral cutting movements can represent more than half of all movements observed in one of the sporting activities. For part 2 an investigation with three systematically varied shoes was undertaken. The results show that with altered shoe sole constructions (torsion and change of shape of the shoe-sole) the supination movement with shoes comes close to the barefoot values. In respect of abduction/adduction of the foot the systematic changes of the shoe soles had no measurable influence.
